We divide 539257 by 20
We're looking to find how many times 20 goes into 539257.

Moving on to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 20

Advancing to step 2:
20 can be fit into 53 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 53, we end up with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 20

Moving on to step 3:
If we divide 139 by 20, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 120 from 139 to get 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 20

Step 4:
192 divided by 20 is 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 269.0
If we take 180 away from 192, we end up with 12.
Include the next digit (5) from the dividend after 12, then repeat: 125 / 20

On to step 5:
125 divided by 20 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 2696.0
Subtract 120 from 125 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Moving on to step 6:
When dividing 57 by 20, we get 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 26962.0
If we subtract 40 from 57, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
The number 20 fits into 170 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 26962.8
Deduct 160 from 170 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 26962.85
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 26962.85
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26962.85
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 26962.85, with a leftover of 0.0.
